Forbidden Siren 2

Like its predecessor, Forbidden Siren 2 is divided into numerous scenarios, organized chronologically in a table called the "Link Navigator". In order to complete a scenario, the player must accomplish a primary mission objective that usually involves reaching an exit point, subduing certain enemies (called "Shibito" and "Yamibito"), or finding an item. Objectives in different scenarios are interconnected via a butterfly effect, and a character's actions in one scenario can trigger a secondary objective in another.
